Description

Novel long service life's automobile bearing subassembly

Technical Field

The utility model relates to a bearing processing technology field, in particular to novel long service life's car bearing assembly.

Background

The bearing is a component for fixing and reducing the load friction coefficient in the mechanical transmission process. It can also be said that the member for reducing the friction coefficient during power transmission and keeping the center position of the shaft fixed when the other members are moved relative to each other on the shaft. The bearing is a lightweight part in modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load of equipment in the transmission process. The bearing assembly in the prior art has relatively large clearance, the bearing is in direct contact with the shaft core, and the bearing assembly can generate large vibration and noise in the use process and has short service life.

The utility model provides a novel long service life's car bearing subassembly.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve among the prior art bearing assembly clearance relatively great, bearing and axle core direct contact can produce great vibration and noise in the use, and the technical problem that life is short provides a novel long service life's automobile bearing assembly and solves above-mentioned technical problem.

A novel long service life's car bearing assembly which characterized in that: the bearing comprises a bearing body, a bearing outer ring, a shaft core sleeve and a bearing sleeve, wherein the bearing body is divided into an outer ring and an inner ring, the shaft core is arranged on the inner ring of the bearing body, the shaft core sleeve is arranged on the outer side of the shaft core and is in contact with the inner ring of the bearing body, the bearing outer ring is arranged on the outer ring of the bearing body, the bearing sleeve is arranged on the outer ring of the bearing body and is in contact with the bearing outer ring, mounting holes are formed in two ends of the shaft core, and a limiting boss is arranged at one end of the.

Preferably, the shaft core and the bearing body are made of stainless steel or alloy steel.

Preferably, the shaft core sleeve and the bearing sleeve are made of wear-resistant rubber.

Compared with the prior art, the utility model has the advantages that: the utility model provides a bearing assembly is equipped with wear-resisting rubber's bearing housing and axle core cover, the bearing housing is located between bearing inner race and the bearing outer ring, axle core cover establish with bearing inner circle and axle between the core outside, avoid bearing and axle core direct contact, reduce the frictional force of axle core when bearing body inner circle rotates, avoid the wearing and tearing of axle core and bearing body, be equipped with axle core cover between the two, borrow this and reduced the clearance of bearing and axle core, avoid producing vibration and noise at the operation in-process, prolong the life of bearing assembly, the use of axle core cover and bearing housing, the leakproofness of bearing assembly has been increased, avoid impurity to get into lubricating oil, influence the lubrication characteristic, produce wearing and tearing to bearing body and axle core, further prolong the life of bearing assembly. The utility model provides a bearing assembly simple structure, installation easy operation, labour saving and time saving.
